6. São Miguel Island
This gem of an island is no doubt one of the loveliest places to have your Portugal honeymoon. You won’t run out of fun, romantic things to do here. Take a dolphin- and whale-watching tour off the coast for an up-close view of the adorable sea mammals. For a natural spa experience that’s sure to heat the blood, visit the geothermal pools of Terra Nostra Botanical Park. In fact, São Miguel is full of similar thermal pools and is just dripping with lush green hills and crystalline lakes to explore, creating a romantic backdrop for your holiday.
